Adaptive Wide Angle

Bank in 2019, you posted a lesson using Adaptive Wide Angle to improve perspective and work with, I believe, vanishing point.

I have an image of the Amber Room that shows the effects of a wide angle lens so that perspective needs help. I followed your guidance from the lesson and improved the image, I think, by a lot. I will upload two jpg files named before and after.

Unfortunately, by the time I finished doing my work the image had lost information from the top and bottom. I wish I could fix the image without losing data. Can you help me with that?
